Butterfly Metamorphosis and Biology

The video explains the complete metamorphosis of a butterfly, known as holometabola, which includes four stages: egg, larva, pupa, and imago. It begins with the egg stage, where female butterflies lay eggs on host plants. The larva stage follows, characterized by active feeding and growth. The pupa stage involves transformation within a chrysalis, leading to the final imago stage, where the adult butterfly emerges, dries its wings, and begins to fly. The video encourages viewers to engage with the content and explore more about metamorphosis.
